a number of things have been suggested and I am following up on all of them.

"If" can work out the logistics we will be at the Noble OK Lucas race with bias tires mounted.

Will post updates.

This is also something to check if your wheels are to close to
neutral or in set you best have very good front end parts.
This is something street rodders deal with a lot with straight
axles, just replace the wheels with more offset and their fine.

Big,

per super stock rules it has factory front suspension [ "A" arm style system, same system as the G body Malibu, Cutlass , Regal ]

Front wheels are 4" wide and centered.

It still applies you need to imagine a line though each
ball joint to the road surface, it make no different if it's
straight axles , a-arm w/ball joints or McPherson stud
it still applies.

Assuming you are using radial slicks ( as the car is an auto ) , are the front tires radials also ? radials and bias ply tires don't play together well !

The Hemi guys were having that problem a ways back, anybody know if they found a solution?
